2024-06 Removing product endpoints from v0.9 API

As was communicated to users in February, we are sunsetting the deprecated product endpoints in the v0.9 API.

The sunset date has now passed, and those endpoints are no longer usable. From today you will start to receive a 410 Gone response for requests to any of the /api/products endpoints.

Replacement endpoints for retrieving and modifying product data are available in the v2.0 (and newer) APIs.
